Youtube should automatically generate the SDR versions if the upload is HDR. When you provide a custom LUT it will use that otherwise it does a default tone mapping. Perhaps there is an issue with the custom LUT if a custom LUT was used.All it shows for me, oddly, are the HDR sizes as shown above. There is no option for viewing SDR, at least not under the gear symbol. Is there another place on the YouTube interface to change that?
